Description
Technical field
The present invention relates to artificial leather covering material technical fields, relate in particular to a kind of for PU synthetic leather rear section technique
Cloudy surface metallic luster aqueous polyurethane inorganic agent and its preparation method.
Background technique
Currently, synthetic leather is with its good physical property, such as good resistance to tortuosity, excellent resistance to ag(e)ing, abundant
Color and skin emulation effect true to nature, have been widely used for the numerous areas such as clothes, luggage, footwear, electronic product.Together
When, the defects of untreated synthetic leather is stiff single, feel is poor and gas permeability is bad there is also color, therefore synthetic leather is adding
Work at the terminal consumer goods it is previous as to be surface-treated, inorganic agent used be " synthetic leather surface treating agent " or " leather
Finishing agent ".
The style of existing synthetic leather surface treating agent is varied: polishing style throws burnt style, velvet style, cloudy surface wind
Lattice, the discoloration of crazy horse, Niu Ba, sheep bar etc..Treated, and synthetic leather is extremely close true in terms of vision, tactile and gas permeability
Skin, and applied for many Chinese patents, such as: a kind of applied " the use for synthetic leather mist of Jiangsu Bao Ze high molecular material Co., Ltd
Puckery waxy-feeling treatment agent in face and preparation method thereof " (number of patent application CN201510760101.3), " a kind of use for synthetic leather cloudy surface is polished
Inorganic agent and preparation method thereof " (number of patent application CN201510759721.5), " at a kind of puckery wax sense of use for synthetic leather sheep bar cloudy surface
Manage agent and preparation method thereof " (number of patent application CN201410307678.4) etc..The synthetic leather treatment agent mist of these patented inventions
Face effect is good, style varied, but is mostly using organic solvents such as methyl ethyl ketone, toluene, dimethylformamide, isopropanols as diluent
Oily treating agent can bring huge pressure to environment in process.
With increasingly influence of the attention industrial products to environment both at home and abroad, the cry of synthetic leather treatment agent Water-borne modification and day
It is all to increase.Some patent literature report about aqueous treatment agent domestic at present, as Jiangsu Bao Ze high molecular material has
Applied " tender skin feel treatment agent of a kind of aqueous PU of use for synthetic leather and preparation method thereof the " (number of patent application of limit company
CN201210297989.8), Ketian Chemical Co., Ltd., Hefei City is applied " for rolling the aqueous polyurethane mist of PVC leather
Surface treatment agent and preparation method thereof " (number of patent application CN201410058025.7), the large many high molecular material science and technology in Xiamen City have
Limit company applied " aqueous to burn inorganic agent and preparation method thereof " (number of patent application CN201310126453.4) etc., although
The related Waterborne synthetic leather inorganic agent of these inventions realizes the Water-borne modification of diluent, but in atomized surface effect and gloss still
It can not compare favourably with traditional oily treating agent；In addition, due to sharply increasing the surface tension of system using water as solvent,
In order to keep the wetting effect to substrate and pigments and fillers, needs to have increased significantly the ratio of wetting agent, both increases cost in this way,
Also reduce the applicability of inorganic agent；Furthermore the partial size for the flatting silica that the inorganic agent uses does not have strict control, cause to handle
Extinction and the transparency cannot be taken into account after agent is covered with paint, lacquer, colour wash, etc., and being reflected on black synthetic leather i.e. mist degree cannot get both with blackness, make to synthesize
The visual experience of leather substantially reduces.
Summary of the invention
In view of the foregoing, the present invention provides a kind of aqueous poly- ammonia of the cloudy surface metallic luster for PU synthetic leather rear section technique
Ester inorganic agent and its preparation method, the embodiment of the present invention are few selected from propylene glycol methyl ether acetate, diethylene glycol dimethyl ether etc. by introducing
Non-pollution solvent is measured as cosolvent, and using the particularity of its molecular structure, is provided simultaneously with hydrophilic lipophilic group, it can be significant
The surface tension that ground reduces system effectively reduces cost to reduce the additive amount of wetting agent, dispersing agent, increases production
The applicability of product.Secondly, the embodiment of the present invention has carried out strict control to the partial size of the flatting silica and fumed silica that use,
Via the transparency for using vapor phase method flatting silica that can guarantee coating, vapor phase method flatting silica and fumed silica are furthermore controlled
